HYnRocARioN BURNER.

Application filed November 2'0, 1925. Serial No. 70,277.v

My present invention pertains to hydrocarbon burners, and contemplates the provision of such a burner which while simple and inexpensive in Construction yis f highly eiiicient in operation.

To the attainment of th-e foregoing, the' invention consists in the improvement as hereinafter-described and definitely claimed.

In the accompanying drawings, forming part of this speciiicatiom-` f Figure 1 is a longitudinal sectional `view illustrative of the construction constituting the best practical embodiment of my invention of which Iam cognizant.

Figure 2 is an enlarged transverse section taken in the plane indicated by the line 2-2 of Figure 1.

Figure 3 is anfenlarged front end elevation Aof the burner.

Similar numerals 'of reference designate corresponding parts inv all of the views of the drawings. l y l Among other elements the yburner comprises a casing body 1, the rear end of which is closed vby a disk 2 welded at 3 or other-vv wiseiixed in the rear end of the casing body. At its forward end the said body is provided with a tapered portion 4, terminating in aV nozzle 5, which is fashioned as best shown in Figure 3. and is provided in its opposite edge portions with kerfs 6. As will be readily understood the flat character of the nozzle 5, and particularly when the said nozzle is kerfed as designated by 6', the nozzle will have the capacity of spreading the flame as is desirable.

llV'elded or otherwise appropriately fixed at `7 to the taper portion of the casing body 1 and also welded at 8 or othrewise appropriately secured in the disk 2 is what I designate the steam and oil conducting and heating pipe 9 ofthe burner. Said pipe 9 occupying the longitudinal center of the burner, communicates at its forward Iendr with the nozzle 5, and extends through the disk 2 and is provided at 10 with a reducer by which it is joined to a pipe 11, designed to lead steam from a source of supply. At the point 12 in rear of the disk 2,l a pipe 13 leads from the pipe 9 and through the disk 2 to the lower chamber 14 of the burner, the said chamber 14 and the upper chamber 15 being separate throughout the major portion of the length ofthe casing body 1by the pipe 9 in association with partition' portions 16, Figures 1 and 2. yThe forward end portion Vof lthe pipe is, by preference, welded yin Ythe dis'l 2. As will be readily understood by reference to Figure 1, ther u 1,6001521v UNITED STATESk the passage of oil or hydrocarbon from the Y upper chamber 15 to the lower chamber 14,

the said passage being as illustrated in transversey coincidence with the forward taper` portion of the casing body 1 which'is manifestly desirable because the v hydrocarbon takes the course mentioned in close -proximity to the point where the combustion of hydrocarbon is takingl place. In thisway the oil en route between the chamber 15 and the chamber 14 is heated and renderedmore volatile, and hence better' adapted tok be com-` mingled with the steam to form a highly inflammable vapor. In its longitudinal passage toward the rear of the chamber 14, the hydrocarbon is further heated by contact with the exterior of the pipe 9 whiohis always heated when the burner is in act-ion, and hence the oil will not come into contact with the' steam until the oil or hydrocarbon is in an adequately vheated or preheated state. I would also have it understood in this'connection that in itsA forward passage longi tudinally of the vchamber 15 the oil will also be heated to a certain extent.

A pipe 18 is'designed to be connected with a suitable sourceof hydrocarbon supply and to conduct hydrocarbon in to the rear portion of the upper chamber 15 in the casing The hydrocarbon is forced through thel tapered end or forward portion of the c asingbody '.1 and around the forward portion of the pipe 9, and then passes rearwardly in"- the lower chamber 14 to the pipe. 13, the hydrocarbon manifestly being heated to a considerable extent while taking the said' course. The steam passing through the pipe 9 Aoperates to entrain the hydrocarbon, and after traversing the pipe 9 the commingled steam and hydrocarbon in the form of a vapor will be discharged through the nozzle 5. Being heated as stated en route between the pipe 18 and the nozzle 5, the hydrocar-lY bon When it reaches the said nozzle 5 will be practically at ignition point and Will affordv a steady and hot flame.

My novel burner manifestly is adapted to be used for the firingof boilers or for any other use to Which hydrocarbon burners are ordinarily applicable.

` Notwithstanding the capa ity of function ascribed to mynovel burner, it will be noted that .the sameis" simple and strong in con.-

struction' and at the same time is compact and adapted'to be operatedwith but mini-f mum 'amount of attention. Y,

The construction herein illustrated and described'in detail isV the best construction of which Iam aware'. Ldo not'desire, how# ever, to'A be understood as confining myselfy tolthe specihc construction and relative arrangement of parts, my invention'being de- `fined by my appended; claims Without. the

scope of Whichstructural changes and `moditicationsin arrangement may be made Withoiit departure from'iny invention.

'Having described "my invention, what I claim and desire to secure by Letters Patent,

l., A hydrocarbon.,l burner comprising a casing body With a forward tapered portion terminatingin a flatnozzle having lrerfs in its opposite edge portions, the rear endof the casingA body'being closed, a longitudinal central vtube fixed at its for'yvardend in the taperpor'tioniof`the .body and extending rearwardly through the 4closed end of thev body and adapted to be connected witha source of steamsupply, partition portions located at'opposit'e sides of the longitudinal central pipe andextending from the closed rear end ofthe body to apointin rear of thev forward taper portion of the body, whereby a passage for hydrocarbon is. afforded. intransverse coincidence with the taper portion of the body, a pipevadapted to be connected. yvith a source of hydrocarbon supply and extending through the closed end of the body and into` the body at'one side of the partition portions and a pipe leading from the rear portion ofthe bodyv atthe opposite side of the"partition portions and communicating with the longitudinal central pipe `vat a vpoint in rear ,of` thej'casing body.

2. el hydrocarbon burner comprising a casing body with a forward tapered. portion terminating in a flat nozzle having lerfs in` its opposite edge portions, the rear .end of the casing body being closed, a longitudinal central tube lixed at its rforward end in the taper portion of the body and extending `rearwardly through the closedend of the body and adapted to be connected With a source of'steam supply, partition portions located at opposite sides of the longitudinal central pipe and extending from theclosed rear end of the body to a point in rear of the forward taper portion of the body, wherebyr a passage for hydrocarbon is afforded 1n;

body, and the closure at therear` end ofthe casing body being in the, form of a, disk Welded in the rear end of said bOCly.

3. A hydrocarbon burner comprisingV a casing bony raving a forward taper portion terminati ina nozzle, means inthe casing body dividing the same into longitudinal chambers, said means including alongitudinal pipe lentending throughout the length ofV the body, and also including a portion'eX-v Vtending fromethe' rear end of thebody to a point spacedinrear' of theinozzle, means forV supplying hydrocarbon 'to onejof said chambers in the rear portionthereof, anda conduit leading freni the rear i,i'ortiofn ofthe other chamber Ato the lirst-'namedfpipe at a,

point in rear of the'casing body.

l. A casing body ior, use in ahydrocarbon burner, having a tapered--forwardY portionv terminating in a nozzley andalso having loro gitudinal chambers in communication oppo ite or in transverse coincidence With said taper portion,iin combination With'a conduit Y for steam leadingl through 'the bodyf and, communicating 'with the nozzle, means for supplying hydrocarbon to oneof Vthe cham bers at a pointremotefrom the nozzle, and a conduit lfor leading hydrocarbonffrom the otherI chamber at a point remote from the nozzle to th'e hrst-namjed conduit.
